J

, I111 the'studsof that kind nowinnse, the ;male member ofthe stud comprises arounded head which enters the female-memberand is kept in position by the tension of resilient blades, which engage the 'male member; The result is that, :when the stud is new, if

the resilient blades or springs aretoo strong,

it is very difficult to separate the members of the said stud, and 'the.c1othes or articles towhich the stud is attached are therefore frequentlytornp On the other hanth'a tter certain use, the" springs deteriorate and; are noilonger strong enough to-keep thestud in its closedposition. I v My present invention intends to remedy these defects, and comprises a femalemember having an eccentric ooening, which.

opening is arranged to receive the head of;

the male member, and merge into a recess of smallerjwidthh. A spring is provided-for keeping the male memberin thesaidrecess in order to prevent any direct unintentional removal of themale member, and to enable the opening of said-studtovbe accomplished by a lateral rather weak conveniently di-' rected pressure uponthe said male. The accompanying drawing shows some embodiments of the stud according to my invention.

Fig. 9 representsa modified, form ofa The female member of the stud comprises slot 2 which adjoins faninletyoperiirig 4. This openingt is eccentrically disposed. in

:the head 3 of the male member enters. This blade 5 'is bent so thatgits free end 6 may move in a slot 7 which a'djo'ins'the opening. 4-; diametrically opposite the slot '2, and is arranged to partially cover the inlet opening 6O 'awdisc o'fjmet'al'or' otherjsuitable material, torminga base 1, which maybe secured-to an article in any well gknown or approved 1 -manner. [The base l' has a centrally located theibase and: of a size to'co-nvenientlyiadmit Y therethrough the-:roundedf head 3 'of'the L in the base] The resilient blade" 5 has an opening 8 through which the rounded head 3' of the male; member enters and is j. locked tive position} The free end of thezblade 5 is suitablvbent, as shown} at 9, to prevent,

to aj'certain .degree rthe' unintentionaldisplacement of-the male member 3.

;The male memberB is mounted one disc surrounds thehead, and is, arrangedto house the end '6 of theiblade' 5, when;themembers" are assembled, as jin use};

In order to unite the members in coactive irelation,.the;head 3 of the male member is caused to enterthe circular opening 4 of the base 1, and engage the bent'portion 9 ofthe resilient blade 5, which will be-forced in the roun'ded'head of the male member, there by causing the latter to slide in the opening 4 towardand into the slot 2. In this posi' 10 provided witha circular groove 11 which 7 tion, the slot 2 engages the neck of-the male locked engagement, the male qmember is moved laterally; out of the slot, whereupon the head 3'abuts the bent portion 9. ofthe blade 5 and depresses the same, sothatwhen the head 3- registers 'with the, opening 4 of the base 1,1the tensionexerted by the .7110 H oi the base 1.

blade 5 will cause the head to pass thereto the article upon which they are to be used by any w ll known or approved manner The form of the members may-also vary ac cording to the requirements. In the form shown in Fig. 6, the resilient blade 5 is cut from the base 1 in spiral form and has a free end 12 disposed above the opening 4: Abutments 1d are provided on the base 1 to cause the :head3 to register with the opening 4 when mo-ved la-terally in the direction to be disengaged from the base 1.

- In the form shown in Fig. 7, I provide a resilient blade 13 which is bent into a suitable form and is arranged to move'above the opening a and allow a lateral pressure sufficient to hold themembers in intimate contact.

In. the form shown in F ig. 8, the base I has a slot 2 and an enlarged opening which is extended laterally therefroi'n and is of a width in one direction to conveniently receive the head-3 of the male member, and permit the head to move a distance therein, .at right angles thereto. i

In Fig. 9,1 have shown a modified form of head oithe male member, which head is I rounded to merge into its neck.
